Abstract

This study aims to assess Counterfeit Situation of Pesticides in Egypt, through investigating and monitoring the counterfeit pesticides widely used in Egypt. And that was done by studying and analyzing different pesticide Formulations (9 active ingredients) collected from different represented regions from the Egyptian market, namely (abamectin, acetamiprid, azoxystropine, carbendazim, chlorpyrifos, cypermethrin, diazinon, difenoconazole and dimethoate).
The labels of the packages of these pesticides were checked to detect their compliance with the data according to the official form, and the samples were analyzed by HPLC and GC to determine the percentage of the active substance and its conformity with the percentage declared on the label for each product. On the other hand, GC-MS and FTIR devices were used to determine the fingerprint of each pesticide and to indicate there are other active ingredients in the contents of the product. Also, the physico-chemical properties of these samples were determined before and after storage by following the international standard methods according to the type of formulation where (emulsification, Suspensibility, wettability) were tested.
The survey was conducted through a questionnaire that was prepared by suitable method for three categories representing farmers, traders, and researchers from university professors and research institutes specialized in the field of plant protection. In the survey, 100 questionnaires were used for each category. The questionnaire was prepared by assembling each group of questions that serve the same purpose in one axis, and each type of questionnaire was divided into several axes, and the results were extracted from the responses received from each category and presented in tables especially and statistically analyzed by suitable method.
The results obtained from the aforementioned tests and questionnaires can be summarized as follows:
First: the status of the targeted pesticide formulations.
1- Abamectin formulations.
Seven samples of Abamectin formulations (obtained from the Department of Pesticides Control – Central Agricultural Pesticides Laboratory - Agricultural Research Center), the results showed that,
A- three samples were not registered through Egyptian Agricultural Pesticides Committee thus representing 42.86% of the total tested samples. The non-registered products are Komaktin Gold Plus, Super Vertimic and Abamectine Strela. Three samples have registration number as other formulations already registered in Ministry of Agriculture which are Abamectin Super, Farmactine and Abamectin power. The last product (Tinam) has the correct registration number (no.1391) and it is the same number used to register it in Ministry of agriculture.
B- The percentage of the active ingredient in 5 samples was less than the acceptable limits, which were (Abamectin super, Komaktin Gold Plus, Abamectin Power, Super vertimic and Abamectine strela) active ingredient content was 1.416, 0.64, 1.01, 0.2 and 0.12% respectively. One sample (Farmactine) didn’t contain Abamectin, and the sample (Tinam) was within the acceptable limits (1.53%).
C- The results of the analysis using LC-MS to detect the active ingredient (Abamectin) indicated that all samples contained abamectin by differ ratio between the molecular weight 859 and 873.
D- The data of analysis using GC-MS to determine the presence of any other active substances inside the samples showed that Abamectin Super sample contains (Lambda cyhalothrin at R.t. 29.512 min), Farmactine sample contains (Fenpropathrin at R.t. 28.634 min), Abamectin Power sample contains (Diazinon at R.t. 16.088 min and Cypermethrin at R.t. 26.554 min) and Super Vertimic sample contains (Fenpropathrin at R.t. 23.916 min and Lambda cyhalothrin at R.t. 34.85 min). Three products Komaktin Gold Plus, Tinam and Abamectine Strela didn’t contain other active ingredients.
E- The results of the emulsification test before and after storage showed that there are 4 identical samples (Abamectin super, Farmactine, Abamectin Power and Tinam) showed good emulsion characteristics before and after storage. Super vertimic and Abamectine strela samples showed poor emulsification characteristics before and after storage. Komaktin Gold Plus showed good emulsification before storage but poor emulsion characteristics after storage.
2- Acetamiprid formulations.
Four samples of Acetamipirid preparations were collected (obtained from the Department of Pesticides Control – Central Agricultural Laboratory of Pesticides - Agricultural Research Center) and the results obtained showed the following:

The non-registered products are Mospilan 25% SP, Acetaplan 25% SP production date (1/5/2016) and Acetaplan 25% SP production date (20/1/2015). The last product (Mospilan 20%) has the same registration number of the correct one (no. 959).
B- The percentage of the active ingredient in all samples was less than the acceptable limits, The samples were [Mospilan 20% SP, Mospilan 25% SP, Acetaplan 25% SP production date (1/5/2016) and Acetaplan 25% SP production date (20/1/2015)] active ingredient content was 12.92, 9.1, 0.563 and 0.64% respectively.
C- The data of analysis using GC-MS showed that Mospilan 20% SP sample contains (Cyclododecane at R.t. 12.09 min), Mospilan 25% SP sample contains (Lambda cyhalothrin at R.t. 24.64 min Deltamethrin at R.t. 28.287 min), Acetaplan 25% SP production date (1/5/2016) sample didn’t contain other active ingredients and Acetaplan 25% SP production date (20/1/2015) sample contains (Malathion at R.t. 22.951 min).
D- The wettability test was identical before and after storage in all samples under study.
3- Azoxystrobin formulations.
A- One expired sample of Azoxystrobin was collected from (Giza Governorate). The results obtained from examining the packaging data and the label showed that the sample is registered through the Egyptian Agricultural Pesticides Committee (No. 1846), but it is an expired sample.
B - The percentage of the active ingredient in the sample was less than the acceptable limits, and the sample content of the active ingredient was 20.9%.
C- The data of analysis using GC-MS showed that Sardo sample 25% SC was found to contain (Difenoconazole at R.t. 27.96 min).

Second: Analyzing the results of the questionnaire responses.
A- The answers of about 90% of the total surveyed groups indicated that the reasons for the spread of the phenomenon of pesticides adulteration in Egypt are due to
• The weakness of the control level
• Selling in unlicensed stores
• The lack of farmers knowledge about different pesticides
And about the effects caused by pesticides adulteration :
b- About 63% of the total surveyed groups decided that generic pesticides lead to the deterioration of the agricultural environment, 56% indicated that they cause the deterioration of the pesticide industry in Egypt, and 59% of the respondents also decided the economic damage to farmers, the deterioration of the health of consumers, farms and animals.
